drm/amdgpu: new ids flag for tmz (v2)
Allows UMD to know if TMZ is supported and enabled.
This commit also bumps KMS_DRIVER_MINOR because if we don't
UMD can't tell if "ids_flags & AMDGPU_IDS_FLAGS_TMZ == 0" means
"tmz is not enabled" or "tmz may be enabled but the kernel doesn't
report it".
v2: use amdgpu_is_tmz() and reworded commit message.
